Answer:
The left ventricle of your heart is larger and thicker than the right ventricle. This is because it has to pump the blood further around the body, and against higher pressure, compared with the right ventricle.
Veins carry blood toward the heart. After blood passes through the capillaries, it enters the smallest veins, called venules.... This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the veins has less pressure than in the arteries.
